HENRY A. WEBSTER, OF MILFORD, MASSACHUSETTS, ASSIGNOR, BY DIRECT ANDMESNE ASSIGNMENTS, TO GEORGE E. W. LUEHRMAN, OF ST. LOUIS, MISSOURI.

WBINGER.

Application led July 29, 1920.

Toallwhomz'tmay concern: y

Be it known that I, HENRY A. WEBSTER, a citizen of the United States,residing at Milford, Worcester County, Massachusetts, have invented anew and useful Wringer, of which the following is a specification.

This invention relates to wringers.and has special reference to amechanism for quickly releasing the pressure devices of the wringerrolls, whereby the pressure devices may be quickly released wheneverdesired, as in case of an emergency.

An object of the invention is to provide a wringer with equipmentcooperating with the pressure devices for the wringer rolls, whereby thepressure may be quickly released in ya more convenient manner fromeither side of the wringer than is possiblel in wringers of ordinaryconstruction.

Other objects of the invention will appear from the followingdescription in which reference is made to the drawing showing apreferred embodiment of the invention, and in which- 1 Fig. 1 is` a planview of a wringer equipped with my present invention.

Fig. 2 is a side elevation thereof with parts of the wringer framemembers in section, and with the wringer rolls pressed together.

Fig. 3 is a similar elevation showing the pressure devices released andin position in which they do not press the rolls together.

As shown, my invention is embodied in a wringer `comprising a framecomposed of a vertical member 1 and a cooperating vertical member 2,said vertical members being joined by connections 3. The lower wringerroll 4 is supported on and may be driven by power a plied to a shaft 5at one end thereof. he opposite end of the shaft 5 is equi ped with apinion 6 meshing with and riving a inlon 7 which is secured to the shaft8 o the upper roll 9 of the wringer. The shaft 8 of the upper roll isjournaled for rotation in vertically movable blocks 10 supported in thevertical end members 1 and 2 of the vertical frame. The roll 9 ispressed to a position of cooperating relationship with the roll 4 by anappropriately shaped leaf spring 11 held in position by the vertical endmembers 1 4 Serial No. 398,703.

and 2 of the wringer frame andacting zltfogainst the upper ends of thebearing blocks spring 11 is engaged-by a pressure bar 12 whose ends areguided for movement by the frame members 1 and 2. By forcing thepressure bar 12 downwardly the spring 11 may be tensioned so to pressthe roll 9 toward the roll 4, but permitting vertical movement of theroll 9 against the resistance of the spring 11 as re uired when theWringer is in use and clot is being passed between the rolls.

A 'bracket 13 is in connection with the upper end of the vertical framemember 1 and has a transverse shoulder 14 under which one end of a crossbar 15 is engaged. The upper end of the vertical frame member 2 1sprovided with a bracket 16 having a recess 17 arranged to receive oneend of a sliding bar 18which is in connection with the cross bar 15.' Aslot 19 is formed in the sliding bar 18 through which the stem of a setscrew 20 passes, said sliding bar being provided with an additional slot21 receiv` ing a screw 22 by which said bar 18 is held in position uponthe cross bar 15. This construction permits movement of the sliding bar18 to and from latched connection with the bracket 16. When the Vslidingbar 18 is in latched connection with the bracket 16 the set screw 2O atone end of the bar 15 and the set screw 23 at the opposite end of saidbar may be adjusted to press the pressure bar 1 2 downwardly as requiredto tension the spring 11 and presses the roll 9 toward the roll 4. Broper manipulation and adjustment o t e set screws 20 and 23 any desireddegree of tension may be lplaced in the spring` 11.

push plate or mk 24 has one end pivoted at 25 to the sliding bar 18 andhas its opposite end ivoted at 26 to one end of a link or ush p ate 27.The opposite end of the lin or plate 27 is connected to the cross bar 15by a pivot 28490 that by adjustin said plates 24 and 27 in straight orallned position as shown in Fig. 1, the sliding plate 18 will be held inlatched connection with the bracket 16. By breakin the toggle formed bysaid plates 24 and 2 the sliding plate 18 will be released from its Thearcuate central portion of theI The spring 32 is of the expansion typeand` has one end bearing against one of the end walls of the recess 31and the opposite end bearing against a depending projection 33' on thesliding bar 18 and acts normally to press the bar 18 outwardly beyondthe end of the cross bar 15 into latched engagement with the bracket 16.

The toggle action of the plates 24 and 2T results from the fact that thepivot 28 is stationary so that when the toggle is broken the bar 18 willbe unlatched or disengaged :from the bracket 16; and when the toggle isstraightened the sliding bar 18 will be moved outwardly into latchedengagement with said bracket.

I am aware that the specific construction and arrangement may be variedwithout departing from the principle and nature of the invention.

I do not restrict myself to unessential features, but what I claim anddesire to secure by Letters Patent, is

1. In a wringer comprising the combination of a frame, a lowerstationary and an upper movable roller mounted therein, a springexerting pressure on the upper roller, a cross-bar mounted in said frameand adapted to receive the pressure' of said spring, a bar slidablymounted on the top of said cross-bar and adapted to engage under akeeper on the frame at its free end, and a pair of push plates havingoperating surfaces disposed on opposite sides of said wringer frame, andbeingpivotally connected` one of said push plates being connected at itsinner end to said cross-bar and the other at its inner end to the end ofsaid slid ably mounted bar, whereby when the free end of either of saidpush plates is pressed inward, said bar will be drawn inward and releaseits free end from engagement with said keeper and thus releaseone end ofsa1d cross-bar and relieve the pressure of the spring on said upperroller.

2. A wringer comprising, in combination with the upper movable roller ofthe wringer, means including a cross-bar for holding said upper rollerunder pressure in yielding contact with a lower stationary roller, arigid bracket engaged by one end of said crossbar. a latch holding saidcrossbar at the opposite end, a push plate operatively connected withsaid cross-bar and latch for horizontal movement, a spring tendingnormally to press said latch outward and to hold the push plate inoperative position` said push plate being adapted, when pushed inward,to release the latch and therebyY free one end of the cross-bar torelease the pressure on said upper roller, leaving the other end of saidcross-bar in engagement with said rigid bracket.

3. A wringer, com rising a frame, alower A roll mounted in the rame,movable bearing blocks mounted in the frame, an upper roll controlled bsaid blocks, a spring pressing upon said b ocks to hold the upper rollin cooperative relationship with the lower roll, a cross bar mounted inthe frame, a device between said bar and said spring for pressing uponsaid spring, a bracket in connection with said frame, a sliding latchbar carried by said cross-bar for engagement with said bracket, and apair of pivotally con nected push plates, one of which is pivoted tosaid cross bar and the other of which is pivoted to said latch bar,whereby when the end of either of said plates is moved inwardly, saidlatch bar will be moved from engagement with said bracket and thusrelease one end ot said cross bar and relieve the pressure upon saidupper roll.

4. A wringer'comprisin'g, in combination with the upper movable rollerof the wringer, means including a rigid cross-bar extending from end toend of the wringer, for holding the upper roller under pressure inyielding contact with the lower stationary roller, a standard carryinga' keeper, a latch movably mounted on the cross-bar for engaging thekeeper for holding the cross-bar down at one end, and a pair of pushplates projectin out respectively beyond the side faces o the cross-bar,supported on the cross-bar so as to move in a substantially horizontalplane toward the cross-bar, said push plates having a connection withthe latch for sliding the latch to release the same when either push Aplate is moved toward the cross-bar.

5. wringer, comprisin in combination, a spring-pressed upper rol er, arigid crossbar receiving the spring pressure, a frame, a latchdetachably holdmg one end oflthe cross-bar, and an actuating deviceprojecting in a substantially horizontal direction beyond both of theside faces of the cross bar and movably mounted on the cross bar so thatit can be operated by ones hand when held on either side of the crossbar by a substantially horizontal movement toward the bar to move thelatch and release the same, and thereby relieve the pressure on saidupper roller.

6. In a wringer, the combination of a spring-pressed upper roller, apair of stand` ards, a rigid cross-bar disposed between said standardsand receiving 'the spring pressure,
